I will say that Safari seems faster, but this update kind of irritates me more than anything because of them, (Apple and AT&T), finally giving us what they promised in the first place with the personal hotspot feature. Now AT&T is wanting to charge me for the privilege of using the bandwidth that I already paid for that mostly goes to waste every month. I have the 2GB per month plan and rarely use more that 200-500MB of that 2GB so the hotspot feature would allow me to actually use more of what I'm paying for anyway by being able to connect my laptop to it, not more of AT&T's bandwidth. So that being said, I'm not too impressed with this update on my iPhone. _________________Mac Mini 2.3 GHz Intel Core i5, 8GB RAM 500GB HD

I used the tethering app when I had my 2G iPhone jailbroke and it worked well except that Edge is so slow it was almost useless. It didn't kill the battery too much but 3G probably would because you're moving so much more data. So you are right, I'm not sure it would be worth it anyway but I sure like to complain about it. _________________Mac Mini 2.3 GHz Intel Core i5, 8GB RAM 500GB HD
